Fig. 3 isa central vertical section on line 3 3 of Fig. 2, showing the perforations Open. Fig. 4 is a similar view showing perforations closed. Fig. 5 is a sectional view of the cover, taken on line 5 5 of Fig. 7 Fig. 6 is a detail sectional view of the rotary perforated plate, taken on line 6 6`of Fig.`8and showing its form before being applied and secured to the cover.
